Urbach’s tail in the absorption spectra of Cu2GeSe3 semiconducting compound
In the present work we report on the analysis of the Urbach’s tail in pure and Mn-doped Cu2GeSe3 samples having small deviation from its ideal stoichiometry. It is found that the high values of the phonon energy hνp involved in the electrons/excitons-phonon interaction in the formation of this tail...
